  "text": "In this Schedule—\n“check valve” means a device which permits the flow of gas in one direction and prevents the flow of gas in the opposite direction;\n“design pressure” means the pressure which a part of a gas system has been designed and constructed safely to withstand;\n“double-check valve” means a device which consists of two check valves in series and which permits the flow of gas in one direction and prevents the flow of gas in the opposite direction;\n“electrically operated valve” means a device which is electrically operated and opens when the ignition is switched on and closes when the ignition is switched off or the power is otherwise cut off;\n“excess flow valve” means a device which automatically and instantaneously reduces to a minimum the flow of gas through the valve when the flow rate exceeds a set value;\n“fixed gas container” means a gas container which is attached to a vehicle permanently and in such a manner that the container can be filled without being moved;\n“gas container” means any container, not being a container for the carriage of gas as goods, which is fitted to or carried on a motor vehicle or trailer and is intended for the storage of gas for either—\n(a)the propulsion of the motor vehicle, or\n(b)the operation of a gas-fired appliance;\n“high pressure” means a pressure exceeding 1.0325 bar absolute;\n“high pressure pipeline” means a pipeline intended to contain gas at high pressure;\n“pipeline” means any pipe or passage connecting any two parts of a gas propulsion system of a vehicle or of a gas-fired appliance supply system on a vehicle or any two points on the same part of any such system;\n“portable gas container” means a gas container which may be attached to a vehicle but which can readily be removed;\n“pressure relief valve” means a device which opens automatically when the pressure in the part of the gas system to which it is fitted exceeds a set value, reaches its maximum flow capacity when the set valve is exceeded by 10% and closes automatically when the pressure falls below a set value ; and\n“reducing valve” means a device which automatically reduces the pressure of the gas passing through it, and includes regulator devices.",
